Pokémon fans who battle online in Pokémon X and Pokémon Y may experience other trainers who could be using an app to cheat.
A program called the "Battle Analyser" is making its way round the internet and has been used by some to screen an opponent - including their entire party, moves and what a rival may choose each turn during the battle itself, as spotted by NeoGAF.
Of course such an app brings out the potential for widely unfair battles and for the community to become unbalanced if it continues.
What are your thoughts on the app and those using it?
